Scientists and their Tools
Tectonic Plates
Mountains
Volcanoes

?-this is where you find magma-2 key parts: lithosphere- is where it touches the crust, magma- this is liquid rock, magma moves in a circular pattern(convection circle) 2900km thick
Magma

Studies volcanoes
volcanologist

dozen and a couple dozen
How many tectonic plates are there?
100
2 plates push up against each other and create a bent or fold
fold mountain
100
-a volcano that is wider than it is higher -active
shield volcano
200
?-3 main layers-topsoil,subsoil,bedrock/headrock, thinnest layer 70km thick
Crust
200
Studies earthquakes
Seismologist
200
edge of the plate
Boundary
200
2 plates that move apart and lava comes up and hardens to from a mountain shape
- volcanic mountain
200
-a volcano that looks like a cone shaped hill -not active
cinder cone volcano
300
?- solid mass, made up of 2 metals-iron&nickle 1250km thick(radius)
Inner Core
300
Studies rocks
geologist
300
-plates move together -plates move apart -one plate goes under the other one -plates slide past each other(earthquake) -valley on the ocean floor
-converging boundary -diverging boundary -subduction -transform -trendes
300
2 plates push up against each other, one slips and breaks
-block mountain
300
a volcano made up of layers of cinder and lava
composite volcano
400
?- puddin like texture because it circulates around the core this does 2 things-makes the earth rotate & creates a magnetic force 2200km thick
Outer Core
400
-reflects extreme heat
silver fire suit

antarctic plate,south american plate,indo-Australian plate,african plate,pacific plate,eurasian plate,north american plate
400
2 plates push up against each other and form a dome shape
dome mountain
400
-most eruptions happen -tectonic plates are diverging -there's a gap therefore lava flow out
ring of fire
500
?: where the mantle touches the crust liquid part of mantle where tectonic plates are formed
lithosphere
500
-megnetometer
to detect minerals in earth
500
-jagged and irregular shaped -constantly moving
tectonic plates
500
-feature that is much higher than the land around it -group of mountains -4 main mountain ranges -youngest range -tallest range -4 main types of mountains
-mountain -mountain range -rockies,himilayans,andes,alps -rockies -himilayans -fold,block,dome,volcanic
